12/30:Boston Celtics center Robert Williams (quad) has been ruled out for Monday's game against the Spurs. It will be the fourth straight game that the 6-foot-10 rookie will miss. While he was productive in the middle of the month when the Celtics were dealing with several injuries in the frontcourt, Williams doesn't have any fantasy value with the team now fully healthy.--Daniel Benjamin - RotoBallerSource: NBC Sports Boston Report
